Many Hoosiers were fast asleep early Thursday morning when they were jolted awake by their phones.

An Amber Alert was issued from New Albany Police Department at 3:31 a.m. in search of 17-year-old Carrie May Pettay. Cellphone users in Indiana who have Amber Alerts enabled received a notification with a loud tone or vibration.

According to New Albany Police Department chief Todd Bailey, the teen returned home on her own accord safely and unharmed. The alert was issued based on information provided by a third party, and police believed Pettay was in "extreme danger."

She was last seen at 12:09 a.m. Thursday in New Albany — possibly with an adult male and female in a 1999 Toyota Solara.

The New Albany Police Department Criminal Investigations Division is looking into the incident further, and Bailey said there is currently no risk to public safety and no one has been charged with a crime.

To issue an Amber Alert in Indiana, the child must be younger than 18 years old and believed to be abducted and in danger of serious bodily harm or death. The request must be made by the law enforcement agency handling the case, and there should be enough description information available to help locate the child.
